Reaction coordinate density, double well

Figure 15. Transfer dynamics in a double-well potential in two degrees of freedom. Shown are the probability densities in the reaction coordinate (p(/ i,r), upper panel) and the additional vibrational degree of freedom (p( 2, t), lower panel).

From an analysis of a double-well system, Gillan has observed that the equilibrium density of the centroid of the imaginary-time path for the reaction coordinate (t).
